Al-Adil II

Al-Malik al-ʿĀdil Sayf ad-Dīn Abū Bakr ibn Nāṣir ad-Dīn Muḥammad (Arabic: سيف الدين الملك العادل أبو بكر بن ناصر الدين محمد‎‎, better known as al-Adil II) (c. 1221 – 9 February 1248) was the Ayyubid Sultan of Egypt from 1238 to 1240.
When his father al-Kamil, nephew of Saladin, died in 1238, al-Adil II followed him somewhat unprepared. When the country plunged into anarchy, his exiled half-brother, as-Salih Ayyub, seized the opportunity and deposed him. Al-Adil died in prison eight years later.
